As shown on the drawings:

A mechanism accomplishing the objects of this invention is shown on thedrawings and will now be described, it being untaken along the linederstood that details of this mechanism may be considerably varied tomeet the needs of particular installations.

In Figure 14 the reference numeral 1 represents an enclosure such as abank, store, dwelling-house or the like, which is provided withI aplurality of windows, doors and'ot'her openings thereinto, each of which'openings is adapted to be closed against entrance or exit by means of ashield or curtain of -steel or other impenetrable material whichis movedinto protective position by mechanism and in a manner to be describedhereinafter. The main entrance to the room or building which isprotected by this installation is preferably provided with a vestibulesuch as is indicated by the reference numeral 2 in`Figure 14, theentrance to, andthe exit from said vestibule being adapted to beclosedby 'protective shields or curtains of the type lheretofore mentioned. Avdiagrammatic illustration of 'such a vestibule is shown in perspectivein Figure 13, and it will be noted that the coustruction thereof is suchthat the various operatin mechanisms may lbe effectively concealebeneath the Hoor and in the side walls of the vestibule. In Figure 15 Ihave diagrammaticall illustrated a mail car which is adapte for theprotective installation of this invention, said mail car beingdesignated as a whole by the reference numeral 3 and being provided withside door closures 4 of the usual t pe. Extending inwardly from one ofsai closures are lateral walls 5 which afford a vestibule entrance, theend of which is adapted to be closed by a `steel protective curtainembodying the principles of the present invention. The closure 4opposite the vestibule entrance is ofcourse also provided with a similarconW cealed protecting curtain.

In the installation illustrated herein there are two types of protectiveshields or curtains, each of which is preferably constructed ofrelatively narrow strips of steel or other substantially impenetrable,fireproof materialz which are hinged together in the manner mdicated bythe reference numeral 6 in Figure 10. -The protective .shield or curtainfor the outer entrance of the vestibule and the mechanism for operatingthe same will now be' described in detail. Said protective shield whichis indicated by the reference numeral 7 is adapted to be rolled on asuitable roller 8 which is rotatably mounted beneath the floor of thebuilding or other enclosure and which is adapted to be driven throu hashaft 9 and bevel gears 10 and 11, which' in turn are driven from amotor 12 through an automatically operated clutch 13 and'suitablereduction gearing 14 and bevel gears 15 and 1,6, best shown in Figure 2.Secured to the upper edge of the curtain 7 is a reinforcing strip 17,the outer ends of which are formed to slidingly spectlve enga guide rods18 and 19which are re.- y mounted ,on .either side of the door or otheropening and are concealed in- Side the frame thereof.' The vertical.guide rod or shaft 19 is rotatably mounted and is adapted to be driventhrough bevel gears 2()y and 21, and a shaft 22, from a motor 23,through suitable reduction gearing 24 and bevel gears 25 which are bestshown in Figure 2. This drive from the vertical shaft or rod 19 istransmitted through bevel gears 26 and 27 and an automatically operatedclutch 28 to a horizontal shaft 29 which is rotatably mounted above thedoor or other closure and inside the upper frame thereof.

Mounted on the horizontal shaft 29 near4 each end thereof adjacent theshaft-s or rods 18 and 19 are sprocket wheels 30 and 31 which are resecti'vely engaged by sprocket chains 32 an 33 which are connected at oneend to the reinforcing strip 17 on the curtain 7 and which have Weights34 and 35 respectively connected to their free ends, the weight 34 beingAmovable on a guide 36, and the weight 35 being movable on a guide 36.

The protective shield or curtain installation just described is used inconnection with the outerdoor of the vestibule of the ,building, railwaycar or the like, and is the one which is initially set in operation. 'Aslightly different type of protective shield or curtain is used inconnection with the remainder of the doors and windows and is also 'usedat the inner end of the vestibule. These protective shields which arecontrolled automatically by means of mechanism associated with theprotective shield or curtain 7 will now be described. Curtains orshields 37 similar to the curtainl 7'are provided for each of the windowand door frames and said curtains are adapted to be wound or rolled on-rollers 38 journalled on a suitable axial shaft 39 beneath the frame ofthe door or window. The upper end of each of said llt) curtains 37 isprovided with a reinforcing strip 40, the outer ends of which are formedto slidingly engage guide rods 41 and 42 which are mounted inside of theframe of the door or window and parallel to the vertical ortions of saidframe. Suitably journalle above the frame of the doorl or window and inalignment with one edge of the curtain 37 is a pulley 43 anda doublepulley 144 is similarly journalled opposite said pulley 43 and inalignment with the other edge of the curtain 37. Secured to one end ofthe reinforcing strip 40 is a flexible member 45 which may consist ofrope, chain, cable or any suitable material and which extends upwardlyaround the pulley 43 and then transversely to the pulley 44, from saidpulley 44 downwardly to connection with a boss 46 on a weight 47 whichis slidably mounted on a guide rod 48 parallel to the 1rov `of gravitythereon will cause the same to rapidly descend, thus causing a rapidupward movement of the curtain or protective shield 37 to close thewindow orv door in which said shield is applied. rlhe weight 47 isnormally held in raised position by means of a spring latch 50 which isadapted to engage in notches in an extension 51 on the upper end of saidweight and which is adapted to be released to release the weight by alink 52 which is operated through a pivoted bell-crank lever 53. Whenthe curtain 37 is moved into operative position by descent ofl theweight 47 the end of the re.- inforcing strip 40 which slidably engagesthe guide rod 41 contacts a forked arm 54 which is pivotally mountednear the upper end of said guide rod and the movement thus imparted bythis Contact with the forked arm 54 is transmitted to a pivoted lever 55which acts to close a switch 56 connected in the circuit of an electricmotor 57 which is adapted to be manually set in operation to rotate theshaft 89 thereby causing the curtain 37 to be rolled on thejroller 38.\A connection between the shaft 39 and the motor 57 is aorded by bevelgears 58 and 59, an automatically operated clutch 60, a shaft 61 andreduction gearing which is indicated as a whole'by the reference numeral62. Said automatically operated clutch 60 is adapted to be moved intoengagement by means of a suitable fork 63 which is connected to apivotally mounted weight 64, the release of said weight allowing thesame to rotate about'its pivot point and causing the jaws of the clutchto be moved into engagement. Said weight 64 is normally 'held inunreleased or upward position by the engagement of a spring latch 65with notches formed in the upper end of a verltical extension arm 66 onsaid weight. The

release of said spring latch 65 is effected through a link 67 which isoperated by a bell-crank lever 68, one arm of which is pivotallyconnected to a member 69 `which in turn is connected to a link 70extending to the lever 55. As a result of this arrangement, the weight64 is released to move the clutch into operative position upon themovement of the curtain 37 into upward or operative position and theconsequent contacting of the forked lever 54 by the end of thereinforcing strip 40.

`When the'curtain 37 is moved to downward or inoperative position bymeans of the above described operation of the motor 57, the switch 56 isopened and the clutch j 60 disengaged. 'This is effected by thecontacting of a pivoted forked lever 71 by the under side of the end ofthe extension 40. This contacting of said lever 71 acts to rotate thesame about its pivot point, forcing the outer end thereof into Contactlwith a horizontal extension 72.0n the member 69, and thus imparting adownward pull on the link 70 to open the switch 56. At the same time theinner end of the lever 71 is moved upwardly, and this upward movement istransmitted to a pivotal connection with an extension arm 7 3 on saidweight 64, the weight thus being rotatedl upwardly about its pivot pointinto such position that the spring latch65 can again engage in one ofthenotches in the extension portion 66.

This upward movement of the weight 64 is of course transmitted throughthe fork 63 to disengage or receive the clutch 60. Substantiallysimultaneously with the release of the clutch 60, the Weight 47 willhave been moved into position so that the spring latch 50 is engaged inone of the notches in the extension 51 on the weight 47, thusmaintaining said weight in raised position. l

A connection effecting the automatic release of the spring latch 50 toallow descent of the weight 47 and movement of the curtain 37 intooperative'position will now be described. Connected to one end of thebellcrank lever 53 is a link 74 which extends downwardly to a pivotedbell-crank lever 75 and is connected to one arm thereof.

Connected to the other arm of said bellcrank lever 75 and extending'substantially horizontally is a link 76 which in turn is connected toone arm of a pivoted bell-` crank lever 77 which is pivotally mountedadjacent the guide rod 19. Extending upwardly from the other arm of saidbellcrank lever 77 is a link 78 which is connected to a pivoted member79, the outer end of which is adapted to be contacted by the end of thereinforcing strip 17 to be moved upwardly into the dotted line positionshown in Figure 1, thus causinga release of the spring latch 50 throughthe connections just described. j

rlihe particular protective shield or curtain 37 and attendant mechanismjust described are adapted 'to be mounted at the inner end ofthevestibule, but exactly'the same installations are adapted lto be mountedin all of the doors and windows of the particular \enclosure to whichthe installation is applied, and the automatic control for thesecurtains is effected through a pivoted lever 80 similar to the lever 79and mounted theree curtain 37.- A connection from the pivoted lever. 80to the controlling spring latches at the variousdoors and windows iseffected through a link 81 which is connected near the outer end of saidlevery 80 and which extends downwardly to a connection with one arm of apivoted bell-crank lever 82, the other arm of which is connected to alink 83 which affords, through suitable connections adapted to theparticular installation, a connection with the various spring latchessimilar to the spring latch 50.`

Upward'movement of the curtain 7 is eected in the manner previouslydescribed through rotation of the shaft 29 and the connection of saidshaft for rotation is made through the clutch 28 which is held inengagement during the upward movementy of the curtain by means ofapivoted weight 84 which is pivoted at 85 and which is provided with anupwardly extending arm' 86 which is connected to a portion of the clutch28 so that when said weight 84 moves downwardly the clutch 28 is engagedin operative position. When the curtain-7 reaches the upper limit of itstravel, the free end of theweight 84 is again moved upwardly torelease-the clutch 28 by contact of the end of the reinforcing strip 17with a forked extension 87 on said weight which is engaged on eitherside of the *shaft 19. Said weight 84 is held inupward orcclutchreleasing position by engagement of a spring latch 88 with oneof aseries of notches formed in an upward extension 89 on said weight 84. Arelease of said spring latch 88 is effected during the downwardmovvement of the curtain through a link 90 which is connected tosone arm'of a pivoted bell-crank lever 91, the other `arm of which has connectedthereto a link 92 extending downwardly to a pivoted lever 93, the outervend of which is adapted to be contacted by the under side of the end ofthe reinforcing strip-17,1dur ing the downward movement of the curtain.Thus, during the downward movement of the curtain, at the point when thesame has 'been moved downwardly sufficiently to move -into concealedposition, said lever 93 is contacted to release the spring latch 88, theweight 84 is allowed to move downwardly y and again cause operativeengagement oft.. the clutch 28, automatically connecting thev curtain tobe again raised through the operation of' the motor 23. This downwardmovement of thecurtain is also transmitted to a vpivoted T-'lever 94which is moved 'into position to allow the opening of fa switchA 95 inthe'circuit of the motor A12 and at the same time to cause a closing ofa switch 96 in the circuit of the motor 23, thus stopping the motor 12and ceasingthe downward movement of the curtain and at the same timeplacing the circuit of the motor 23 in such position that the curtain 7may again be ra1sed.

The operation of the T-lever or plate 94 is effected through a link 97connected thereto and extending downwardly to a member 98 which has ahorizontal extension 99 extending under one end of a pivoted forkedlever 100 which is engaged on either side of the shaft 18. It will ofcourse be obvious that the downward movement of the curtain causes theund-er side of the end of the reinforcing strip 17 to Contact the forkedend of the lever 100, causing downward movement thereof, said downwardmovement being transmitted through the link 97 to the T-plate or lever94. The dbwnward movement of the forked end of the lever 100 of coursecauses the other end thereof to be moved upwardly, and this upwardmovement is transmitted to a pivoted weight 101, through a pivotalconnection of the o-uter end of said lever `100, with anf upwardlyextending member .102 on said member 101. Said weight 101 is pivoted at103: as the raising of the free end thereof in the manner just describedacts to release the 'clutch 13, a connection between the wei ht and thefork 104. When the curtain 7 is rolled down into inoperative positionsaid weight 101 is held upwardly to maintain the clutch 13 in disengagedposition by the engagement of a spring latch 105 with one of a series ofnotches formed in an upwardly extending' member 106 on said weight 101.When the curtain is moved upwardly into operative position the end ofthe T-plate or lever 94 which is connected to the link 97 is 'contactedby the reinforcing strip 17 and is moved upwardly, thus moving the link97 upwardly, andr this upward movement o-f the link 97 is transmittedthrough a bell-crank lever 107 and a link 108 to release the springlatch 105 and thus allow the weight 101 to drop and move the clutch 13into engaged and operative position. This movement of the T-plate 94 issimultaneously transmitted lclutch being afforded by an or inary 'clutchI to close the switch 95 in the circuit of the motor 12, and to allowthe opening of the switch-96 in the circuit of the motor 23.

As has been before stated, the operating Vmechanisms for'theprotectiveshield or cur- .2,3, 4 and 13, wherein the reference numeral109 represents the inner wall of the building, room or vestibule,wherein the reference numeral 110 represents the ,outer walls thereof.The floor is designated by the reference numeral 111 and narrow openingsin the floor and in the side walls permit of the free upward anddownward movement of the protective shields or curtains. The

narrow opening in the Hoor 111 is preferably normally closed by a hingedstrip or spring door 112 which is pushed upwardly into open position bythe upward movement of the protective shield or curtain. The narrowopenings in the side walls 109 are normally concealed by strips 113which are guided by the side walls themselves and resiliently held overthe narrow openings by light helical springs 114'. The lower ends ofsaid strips 113 are beveled in the manner indicated in Figure 3, so thatthe upward 4movement of the protective shield or curtain will servetopush the same rearwardly out of the way, compressing the springs 114.Said strips 113 are preferably formed in the manner indicated in `Figure4 soas to slidingly engage each side of the wall 109, said wall therebyacting as a guide for said strip. The ceiling of the room or the top ofthe door frame indicated by the reference numeral 115 is preferablyprovided with a groove 116 in which the reinforcing strip on the top ofthe curtain or protective shield is engaged when the same is moved intooperative or protecting position.

Figures 16 and 17 diagrammatically illustrate the electrical connectionswhich are used in the installation of this invention. Figure 16illustrates the electrical connection employed in connection with themotorl 23 which is employed for raising the curl tain 7. Theseconnections include a main contro-l or line switchr117 which ispreferably locked in a control boX' together with other manual controlswitches, the switch 96 which has previously been described and anautomatic or spring operated switch 118 which is placed in position inthe drawer of a cash register, or in conjunction with the door of a safeor vault, or in any other suitable place where unauthorized tamperingwill cause the same to be closed and the circuit completed.

An alarm bell 119 or any other suitable electrically operated alarmapparatus may also be placed in shunt with the circuit so as to ring oroperate when the switch 118 is closedby the unauthorized manipulation ofthe burglar.

The electric circuit for the motor 12 Figure 17) which is like the motor57, is used for returning the curtain to inoperative position, andcomprises a manual control switch 120 and the reset switch 95.Substantially the same circuit is used in connection withthe motor 57,in this case the switch 56 tal;-

.ing the place of the switch 95.

The operation is .as follows:

The' operation of the device will be obvious from the foregoingdescription. IUpon the'closing of the spring switch 118 by the burglaror other unauthorized person, the Circuit to the motor 23 is energized,an'd said motor is set in operation to cause an upward movementof thecurtain 7. This movement is relatively slow and upon contact of thereinforcing strip 17 with the lever 80, Weights similar to the weight 47are released and the windows, doors and other openings are closed bycurtains similar to the curtains 37. This closing of the windows an'ddoors is rapidly effected since the weights like the weight 47 arepreferably made heavy enough to cause a fast upward movement of thecurtain and upon the doors and windows thus being closed, the burglarwill naturally attempt to escapo through the vestibule since the curtain7 has not yet entirely closedand this offers an apparent avenue ofescape. Said curtain 7 however in the meantime has .travelledsuiiiciently high to prevent the burglar escaping therepast andordinarily upon the burglars reaching the vestibule the travel of thecurtain 7 will have been suicient to cause the reinforcing strip 17 .totrip the' lever 79 thereby releasing the weight 47 and causing a rapidupward movement ofthe curtain 37. ln attaining this result the speed ofthe curtain' 7 and the position of thelever 79 are varied in accordancewith the size of the room or other enclosure. rlihus, in a largemajority of cases the burglar is very likely to be trapped in thevestibule during his efforts at escape. The control of the motors forreturning the curtains to inoperative position is of course manuallyeffected through switches simllar to the switch 120 which are allpreferably positioned in a looked an'd concealed compartment. Both inthe upward and downward movement of the curtain the automatic resettingoperations of the switches and clutches are e'ected in the mannerpreviously described.

It will be apparent from the foregoing.

' eration by llawful'.'occupants of the building or the'ilikelinca'se offire to isolate certain rooms of the building or to close the sameagainst 'draughts which enhance the spread of the fire.

It desired, the entire installation may be disconnected for purposes ofrepair or in- -spection by opening the manual control switch' 117.

I am; aware that numerous details of construction n'xay be variedthrough a. wide range'without departing from the principles of this'invention, and I therefore do not .purpose limiting the patent grantedhereon, otherwise than-necessitated by the prior art; III claim as my4invention:
